The study aims to assess the stabilization of ethanol foams using a mixed surfactant system under varying conditions.
Used mixed surfactant system to stabilize ethanol solutions
Compared foam stability under acidic vs neutral conditions
Measured surface shear viscosity to evaluate drainage effects.
Acidic conditions significantly improved foam stability compared to neutral conditions
Higher surface shear viscosity reduced drainage, further enhancing foam stability

Implication

Randomized trial evaluates foam stability in ethanol solutions, highlighting the role of surfactant mixtures.

Abstract

• Ethanol solutions were stabilized using a mixed surfactant system. • Acidic conditions greatly enhanced foam stability compared with neutral conditions. • Increased surface shear viscosity suppressed drainage, enhancing foam stability.
